Hi Tom,
It seems that hiding text and links is a practice outside the Webmaster Quality Guidelines, as stated in the following URL: https://support.google.com/webmasters/answer/66353?hl
This way, how can I also remove these codes from pages:
<li class="search-item" title="Pesquisar"><a href="#"><span class="screen-reader-text">Pesquisar</span></a></li>
<div class="mobile-bar-items">
<span class="search-item" title="Pesquisar">
<a href="#">
<span class="screen-reader-text">Pesquisar</span>
</a>
</span>
</div>
Thanks
